Quadrilateral ABCD is a parallelogram. DE = 6.1 cm and m∠DAB = 120°. Parallelogram A B C D is shown. Diagonals are drawn from point A to point C and from point D to point B and intersect at point E. The length of A D is 10 centimeters and the length of D C is 5 centimeters. What is BC? cm What is m∠BCD? ° What is AB? cm What is EB? cm
Answer:
The answer is below
Step-by-step explanation:
A parallelogram is a polygon (has four sides and four angles) in which opposite sides are parallel and equal to each other. Opposite angles are equal and consecutive angles are supplementary. Also, the diagonals bisect each other.
BC = AD (opposite sides are equal)
BC = 10 cm
m∠BCD = m∠DAB (opposite angles are equal)
m∠BCD = 120°
AB = DC (opposite sides are equal)
AB = 5 cm
EB = DE (diagonals bisect each other at point E)
EB = 6.1 cm
Answer:
BC = 10
m∠BCD?=120
AB=5
EB=6.1

The proper height of a highway guardrail is 27 inches, but 3 inches higher or lower is acceptable. Which inequality represents the acceptable heights, h, of a highway guardrail?
A.|h+27|≤3
B.|h−3|≤27
C.|h+3|≤27
D.|h−27|≤3
Answer:
Step-by-step explanation:
27 is the "center" of a range of measurements of the height of the guard rail. The height could be as much as 30 inches or as little as 24 inches. The absolute value operator encloses "x - 27," where 27 is the "center." The acceptable excess or acceptable deficiency is 3 inches.
So now we can eliminate possible answers B and C, in both cases because 27 is inappropriately greater than 3.
Narrowing down our choices, we have h + 27 and h - 27 inside the absolute value operator. 27 is a positive quantity (height of the guard rail), so the inequality showing +27 as the "center" is correct; that is
D: |h - 27| ≤ 3 (measurements in inches).

The line L1, is y= 5x+1
The line L2, is 2y-10 +3=0
Show how these 2 lines are parallel
Answer:
Step-by-step explanation:
L₁: y = 5x + 1
Slope of L₁ = 5
L₂: Did you mean 2y - 10x +3 = 0 ?
2y = 10x - 3
y = 5x - 1.5
Slope of L₂ = 5
L₁ and L₂ have the same slope, so the lines are parallel.

PLEASE HELP!! SOLVE FOR 7,8,9 IN PART 1 ACTUAL ANWSWERS DONT STEAL MY POINTS!!!! I WILL GIVE BRAINEST TO CORRECT ANWSER
Answer:
Given formula:
d = (21.9) [tex]2^{(20-x)/12}[/tex]1.
Find d(7), d(8) and d(9)
d(7) = (21.9) [tex]2^{(20-7)/12}[/tex] = (21.9) [tex]2^{13/12}[/tex] ≈ 46.404d(8) = (21.9) [tex]2^{(20-8)/12}[/tex] = (21.9) [tex]2^{12/12}[/tex] = 43.8d(9) = (21.9) [tex]2^{(20-9)/12}[/tex] = (21.9) [tex]2^{11/12}[/tex] ≈ 41.3422.
The ratios are
d(9)/ d(8) = 41.342/43.8 ≈ 0.944d(8)/(d(7) = 43.8/46.404 ≈ 0.944As we see the ratios are same. This is due to the exponential nature of the function. 0.944 is the common ratio between two consecutive distances.

Is 6/5 greater than 2/3
Answer:
yes 6/5 is greater
Problem solving:
first you need to simply the fractions and see which one is bigger.
2/3 = 0.667
6/5 = 1.2
-Sumin <3
Answer:
Yes
Step-by-step explanation:
When you look at the two fractions, we can immediately tell that the first is over 1 and the other is not one. However, if we wanted to see how much greater 6/5 is compared to 2/3, then we could find the common denominator and then subtract the 2/3 from the 6/5.
6/5 - 2/3
18/15 - 10/15
8/15.
This can't be simplified.
Thus, 6/5 is 8/15 greater than 2/3.
Hope that this helped and everything works out. You can do this same method with any two fractions if your not sure if one is greater than, equal to, or less than any other number and what the difference is between them.

-2x-5 = 19
I need help with this
Answer:
-12
Step-by-step explanation:
First you add five to the 19 and get 24 and then you divide -2x by 24 and you get -12
Answer:
x=-12
Step-by-step explanation:
-2x-5=19
+5 to both sides
-2x=24
÷-2 to both sides and you get -12
You deposit 10,000 into a savings account that compounds quarterly. The account has an interest rate of 3.7%. What would be the value of the investment after 30 year
Answer:
30189.155
Step-by-step explanation:
Recall the compound interest formula :
A = P(1 + r/n)^nt
P = principal = 10000
r = rate = 3.7% = 0.037
n = quarterly = 4
t = 30
A = 10000(1 + 0.037/4)^30*4
A = 10000(1 + 0.00925) ^120
A = 10000(1.00925)^120
A = 10000 * 3.0189155
A = 30189.155

Someone please Help me!!!!!
Also the dash for the second one is Negative 189. Please Show Step-by-step, thanks. No links.
Answer:
Step-by-step explanation:
The first and only rule really is to factor these down to their primes and then apply a very simple rule
For every prime, take out 1 prime for every prime under the root sign that equals the index. The rest are thrown away.
That's very wordy. Let's try and see what it means with an example
Take sqrt(27) The index is 1/2 (square root) That means we need two threes in order to apply the rule.
sqrt(27) = sqrt(3 * 3 * 3 ) For every two primes take out 1 and throw one away.
sqrt(27) = 3 sqrt(3) You can't take out that 3rd 3.
64 = 2 * 2 *2 *2 *2 * 2
4th root 64 = 2*2*2 *2 * 2 *2
for every 4th root, you get to take 1 out and throw three away.
4th root 64 = 2 fourth root (2*2)
4th root 64 = 2 fourth root (4)
- 189 = - 3 * 3 * 3 * 7
cuberoot (- 189) = For every 3 roots, you get to pull 1 out and throw the other two away.
3 cube (- 7) is your answer.
72 = 2 * 2 * 2 * 3 * 3
cube root (72) = 2 cube root(9) You don't have enough threes to do any more than what is done.
